Path Traversal in RabbitMQ (CVE-2026-67224)
Summary
Path traversal in RabbitMQ (CVE-2026-67224). Risk of unauthorized operations or information disclosure. Exploitable via PUT /api/traces/.
Original description
The description as published by the source.
RabbitMQ is a messaging and streaming broker. Prior to versions 3.13.15, 4.0.20, 4.1.11, 4.2.6, and 4.3.1, The trace consumer constructs the output path as filename:join(TraceDir, Name ++ ".log") where Name comes from PUT /api/traces/:vhost/:name. No safe_relative_path / traversal check is applied on the write side, while the read side (rabbit_tracing_files.erl) does call rabbit_misc:safe_relative_path/1 , proving the omission is an oversight, not design. The .log suffix is forced and the endpoint requires administrator. A user with the administrator tag can write a .log-suffixed file to an arbitrary filesystem path writable by the rabbitmq user via the tracing plugin's name parameter, e.g. /etc/cron.d/x.log (if writable) or overwrite existing .log files outside the trace directory. Preconditions include rabbitmq_tracing plugin enabled administrator tag Target path writable by rabbitmq OS user. This issue is fixed in versions 3.13.15, 4.0.20, 4.1.11, 4.2.6, and 4.3.1.

CVE-2026-67224 (RabbitMQ) — CWE-22
Attack surface: PUT /api/traces/
Plan: 1) Audit SBOM/dependencies, 2) Stage→prod upgrade, 3) Add WAF/proxy monitoring on affected endpoints, 4) Hunt IOCs in logs.
Refs: see the GHSA / vendor advisory / patched release linked on this page.
Path traversal (CWE-22) exists in RabbitMQ. Attackers reach the vulnerable code path via PUT /api/traces/.
Check the vendor advisory for the affected versions of RabbitMQ. Attack surface: PUT /api/traces/.
Severity: ?. Risk of unauthorized operations or information disclosure.
Update to the patched release per vendor advisory.
Until the patch is applied: disable the affected feature, apply WAF rules, or restrict access via network ACLs.
Search webserver/proxy logs for unusual PUT /api/traces/ requests with malformed payloads or SQL meta-characters. Run grep -r 'RabbitMQ' . against your dependency files (package-lock.json, requirements.txt, go.sum) to find affected services.

Concrete steps and command examples for SOC/SRE teams to execute in order
-
1Identify exposure identify
grep -r 'RabbitMQ' . | grep -v node_modulesリポジトリと本番環境の依存ファイル (package-lock.json / requirements.txt / go.sum / Gemfile.lock 等) で
RabbitMQを grep し、稼働しているサービス・バージョンを把握する。 -
2Hunt for indicators of compromise detect
grep 'PUT /api/traces/' /var/log/nginx/access.log | grep -E '(unusual_payload|sqli_pattern)'アクセスログで
PUT /api/traces/への異常なリクエスト (不正な認証ヘッダ・SQLメタ文字)を過去 30〜90日分捜索。WAF/SIEM があれば該当パスのアラート発火履歴を確認。 -
3Post-deployment verification verify
Replay attack against PUT /api/traces/ on staging to confirm patch closes the vectorパッチ適用後、ステージングで PoC または同等の悪用パターンを再現して脆弱性が閉じたことを確認。本番では Step 2 と同じログクエリでアラート再発が無いか継続監視。
